| Sumario: | Constituents of Helenium atacamense Cabr were investigated following a preliminary screening of the biotoxicity against Artemia salina and the antitumoral activity of ethanol extract . Three compounds already identified were isolated from aerial parts of Helenium atacamense Cabr, and their structures were elucidated as helenalin, quercetin and 3-O-methylquercetin based on mass and various nuclear magnetic resonance techniques . Quercetin and 3- O- methylquercetin were tested by using TEAC Test |
